I got the house ending. I never got through the locked or inverted doors and honestly don't have a clue how. Very curious to see the rest of the game though, I may have to return.
the house ending is probably my favorite even though it’s the saddest.
as a heads up, the doors are red herrings, although there was more i wanted to do with them.
for the other endings, near end game, someone is keeping a big secret. see if you can get it out of them :]
